Problems solved by technology

During the extrusion and shaping production process, since the size of the traction force is affected by the extrusion force of the extruder and the friction force of the setting table of the sizing machine, the setting of the traction force generated by the traction machine is completely controlled by the experience of the workers. The sense of responsibility is not in place, the traction force is often set to mismatch, and it is easy to cause waste in the production process

Embodiment Construction

[0009] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0010] The sensing control device of the present invention includes a calibrating table 2 and a pressure sensor 4 .

[0011] The shaping table 2 is installed by rollers, and the rollers are locked during operation so that the position of the shaping table 2 is fixed. Along the direction of the shaping sequence, four shaping plates are arranged on the shaping table 2, and the first shaping plate 2-1 slides The mechanism 1 is installed on the shaping table 2, and the remaining three shaping plates are fixedly installed. Under the action of external force, the sliding direction of the first shaping plate 2-1 is the movement amount in the direction of the force, and the external force is the displacement of the extruder 3. Extrusion thrust, under the extrusion thrust of the extruder 3, the first shaped plate 2-1 has a mov...

Abstract

The invention discloses a sensing control device; the sensing control device comprises a sizing platform, the position of which is locked; a first sizing plate of the sizing platform is arranged on the sizing platform through a sliding mechanism; the sliding direction of the first sizing plate is the moving direction towards a second sizing plate under the extrusion thrust action of an extruder; and a pressure sensor for inducing the stressed movement amount of the first sizing plate and displaying an induction signal on a display of a control system is arranged between the first sizing plate and the second sizing plate. According to the invention, the movement amount of a movable platform is induced through the pressure sensor, so that the extrusion thrust of the extruder is indirectly detected; therefore, production is controlled by adjusting the pulling speed of a tractor on this basis; and in addition, compared with the traditional traction force control only depending on experiences, the product yield is greatly increased.

Description

technical field [0001] The invention relates to a control technology for extrusion and shaping production of plastic products, in particular to a sensor control device. Background technique [0002] The production of plastic products involves extrusion and shaping. Plastic raw materials are extruded through an extruder, shaped by multiple shaping plates on the shaping table of the shaping machine and cooled to become shaped products. During the extrusion and shaping production process, since the size of the traction force is affected by the extrusion force of the extruder and the friction force of the setting table of the sizing machine, the setting of the traction force generated by the traction machine is completely controlled by the experience of the workers. If the sense of responsibility is not in place, the traction force will often be set to mismatch, which will easily lead to waste products in the production process. Contents of the invention [0003] Aiming at th...
